The original move of the mkefidisk code to the bootimg-efi plugin
resulted in a bad hdddir - fix it.

The wic command-line param --rootfs-dir gets generalized to support
multiple directories. Each '--rootfs-dir' could be connected using a
special string, that should be present in .wks. I.e:

wic create ... --rootfs-dir rootfs1=/some/rootfs/dir \
  --rootfs-dir rootfs2=/some/other/rootfs/dir

  part / --source rootfs --rootfs-dir="rootfs1" --ondisk sda --fstype=ext3 \
    --label primary --align 1024

  part /standby --source rootfs --rootfs-dir="rootfs2" \
    --ondisk sda --fstype=ext3 --label secondary --align 1024

The user could use harded-code directory instead of connectors. Like this:

  wic create ... hard-coded-path.wks -r /some/rootfs/dir

  part / --source rootfs --ondisk sda --fstype=ext3 --label primary --align 1024

  part /standby --source rootfs --rootfs-dir=/some/rootfs/dir \
    --ondisk sda --fstype=ext3 --label secondary --align 1024

When a .wks has more than one ROOTFS_DIR it's better to report
all ROOTFS_DIR that was used to create the image.

The do_prepare_partition() method from RootfsPlugin class need
to know what will be the rootfs_dir. This makes sense when .wks
file has a partition set up like this:

  part /standby --source rootfs --rootfs-dir=<special rootfs> ...

then do_prepare_partition() will work with the correct rootfs.

Implement RootfsPlugin class. The do_prepare_partition() method
is implemented using code in Wic_PartData class.

This class have 'rootfs' name, which is the name that should
be used in the --source parameters of the .wks partition commands.

Instead of simply creating partitions large enough to contain the
contents of a --source partition (and adding a pre-specified amount of
padding), use the --size used in the partition .wks statement.

If --size isn't used, or is smaller than the actual --source size,
retain the current behavior.

Remove all the Wic_PartData and DirectImageCreator code now
implemented by the BootimgEFIPlugin and BootimgPcbiosPlugin plugins,
as well as all the special-cased boot_type code, significantly
cleaning up the code.

Replace the calling code with general-purpose plugin invocations, in
essence calling the appropriate implementations at run-time based on
the --source value in effect.

Change the directdisk.wks and mkefidisk.wks scripts to make use of the
new plugins.

Implement the BootimgPcbiosPlugin and BootimgEFIPlugin SourcePlugin
classes.  The configure/prepare_partition() methods are implemented
using code derived from similar code in the Wic_PartData class.

These classes have the corresponding names 'bootimg-pcbios' and
'bootimg-efi', which are the names that should be used in the --source
parameters of the .wks partition commands.

rt_util contains bootstrap_mic(), which imports rpm and other things
we don't need because we don't do bootstrap i.e. runtime (set in
wic.conf) is always set to 'native', which means use what's on the
local host.

bootstrap mode is for downloading and installing rpms that wic needs,
which we may want to implement later; for now, we just want to use
what's local.

Reuses the mic/livecd infrastructure but heavily subclasses and
modifies it to adapt to the special needs of building images from
existing OpenEmbedded build artifacts.

In addition to the OE-specific mic objects and modifications to the
underlying infrastructure, this adds a mechanism to allow OE kickstart
files to be 'canned' and made available to users via the 'wic list
images' command.

Two initial OE kickstart files have been added as canned .wks files:
directdisk, which implements the same thing as the images created by
directdisk.bbclass, and mkefidisk, which can essentially be used as a
replacement for mkefidisk.sh.  Of course, since creation of these
images are now driven by .wks files rather than being hard-coded into
class files or scripts, they can be easily modified to generate
different variations on those images.  They also don't require root
priveleges, since they don't use mount to create the images.  They
don't however write to media like mkefidisk.sh does, but rather create
images that can be written onto media.
